incoming path. Add lengthy comments to explain what we do.

in other methods.
(struct pipe_request): Define.
(struct pipe_reply): Define.
(fhandler_tty_slave::open): Throughout, try to open synchronization
objects with MAXIMUM_ALLOWED permissions. Drop call to cygserver.
Try to duplicate pipe handles via master_ctl pipe if duplicating
directly doesn't work.
(fhandler_tty_slave::cygserver_attach_tty): Remove.
(fhandler_tty_slave::init): Close unused incoming pipe handle.
(fhandler_pty_master::close): Send exit message to master control
thread and close master_ctl handle.

(fhandler_pty_master::setup): Simplify creating pipe inheritance.
Make sure we're the one creating the input_available_event. Add
comment to explain why. Create master_ctl pipe and start master

(tty::exists): Open mutex handle with READ_CONTROL access.
(tty::alive): Remove.
(tty::open_output_mutex): Convert to inline method.

name parameter. Always create TTY_SLAVE_ALIVE event.
(tty::get_event): Take additional PSECURITY_ATTRIBUTES parameter for
CreateEvent.
* tty.h (class tty): Change declarations according to aforementioned
changes.
(tty::open_output_mutex): Implement as inline method.
(tty::open_input_mutex): Ditto.
valid content for ptys. Remove setting FILE_CREATE_PIPE_INSTANCE
in access flags since it's not needed. Set the access mask for
kernel objects according to what's returned by NtQueryInformationFile,
info class FileAccessInformation.
(__seterrno_from_nt_status): Call seterrno_from_nt_status.
* errno.cc (seterrno_from_win_error): Set errno without calling
set_errno to avoid packing strace output with errno messages.
(seterrno_from_nt_status): New function to print NT status as well as
resulting Windows error.
Most the sim write functions declare their source buffer const because
they only ever read from it. The global sim_write() function does not
follow this convention though which causes some warnings when trying to
pass it const strings or buffers.

violation. Explain why we do this.
(fhandler_socket::bind): Create file with no sharing allowed.

to cygserver, rather than the Cygwin PID.
